Title: Amorphous solar cell and manufacture thereof
Inventor: NITTA YOSHITERU
IPC: H01L31/04
Filed: 1989-01-31
Abstract: PURPOSE:To prevent a short circuit between a transparent electrode and a metal electrode by a method wherein a transparent electrode is divided into two or more parts, each of divided amorphous silicon semiconductor layers is formed so as to expose a part of each divided transparent electrode, and each of divided metal electrodes is so formed as to extend to the exposed part of the transparent electrode between the adjacent amorphous silicon semiconductor layers. CONSTITUTION:A transparent electrode is divided into two or more electrodes 2a-2d by the irradiation with laser rays, and an amorphous silicon semiconductor layer is divided into semiconductor layers 3a-3d by the irradiation with laser rays so as to expose a part of each of divided transparent electrodes 2a-2d. And, a metal electrode is divided into electrodes 4a-4d through an etching process so as to extend to the exposed part of each of the transparent electrodes 2a-2d between the amorphous silicon semiconductor layers 3a-3d of adjacent photovoltaic regions. Therefore, the transparent electrodes 2a-2d formed on almost the whole surface of a substrate 1 are not in contact with the island-like metal electrodes 4a-4d, and the parts of the amorphous silicon semiconductor layers 3a-3d exposed through an etching process are protected against damage. By this setup, a short circuit between transparent electrodes and metal electrodes is prevented, so that a solar cell of this design can be improved in reliability.

Title: Magnetic recording medium
Inventor: FUJIMURA TAKASHI
IPC: C09D127/06
Filed: 1990-02-01
Abstract: PURPOSE:To prevent increase of dropout by incorporating nonpolymerizable low mol.wt. org. antistatic agent into a binder by a specified amt. and forming an antistatic layer containing this binder which is same as the binder of a magnetic layer. CONSTITUTION:An antistatic layer 3 is formed on the back side of a magnetic recording medium. Into the binder of this antistatic layer 3, 1-20 pts.wt. of nonpolymerizable low nol.wt. org. antistatic agent is incorporated to 100 pts. of the binder in terms of solid conc., and this binder is same as that in the magnetic layer 2. Thereby, when the magnetic recording medium slides in a magnetic recorder, electrostatic charging in the back side of the nonmagnetic supporting body of the medium caused by friction between the medium and the device is prevented by the antistatic layer 3. Thus, deterioration of magnetic recording/reproducing characteristics and increase in dropout after lapse of time can be prevented.

Title: Grouting by clay
Inventor: SUZUKI TOMIO
IPC: C09K17/02
Filed: 1983-02-17
Abstract: PURPOSE:To make it possible to shorten working time without necessitating the solidification or swelling of a filler and to use a drilling pipe as a filling pipe in combination with a water jet process, by using clay having specific plasticity as a filler. CONSTITUTION:In a grouting process for forming a water stopping layer by introducing a filler into a lost circulation layer under pressure, clay having plasticity of 1.3-1.8t/m<3> is used as the filler. By performing the filling of the lost circulation layer only by clay, the filler material is extremely inexpensive while the hardness thereof can be freely regulated by adjusting the water content and, therefore, the filling of the lost circulation layer having a different void ratio can be filled only by preparing one kind of the filling material. Not only can working time be shortened without necessitating the solidification or swelling of the filler material but also a drilling pipe can be used together with a filling pipe in combination with a water jet process and, if reaching the lost circulation layer during drilling, clay filling can be performed only by operating several valves while drilling can be re-started by the reverse operation after the water stopping layer is formed.

Title: Substrate inspecting device
Inventor: UKITA AKIO
IPC: G01R31/28
Filed: 1990-02-01
Abstract: PURPOSE:To prevent a case that a probe does not come in contact with the terminal of a pattern from being decided as defect of pattern by measuring the resistance of the pattern after confirming that the probe comes in contact with the terminal of the pattern. CONSTITUTION:Supposing that the probe comes in contact with the terminal 11 first, a waveform shown by figure is measured by an ammeter 5 because electrostatic capacity exists between the pattern 8 and a reference electrode 15. In the case that the probe does not come in contact with the terminal 11, the waveform is not measured because the pattern 8 is not electrified. Next, another probe comes in contact with the terminal 12. In the case that the terminal 11 comes into contact with the terminal 12 at such a time, a current flows in the pattern by a potential difference between power sources 13 and 14 and other waveform is measured by the ammeters 5 and 6. When the probe does not come in contact with the terminal 12, none are measured by the ammeter 6. After confirming that two probes accurately come into contact with the terminals by following the above procedure, the propriety of the pattern is decided.

Abstract: PURPOSE:To enable the boring in high accuracy by continuously providing connection parts, each of which has a supporting axis erected on a base and a drill, and rotating it round the supporting axis and rotating a substance to be bored by equal intervals after positioning the drill on the circumference of the substance to be bored. CONSTITUTION:After fastening a substance 7 to be bored with a claw body, a rod is rotated centering round a support 2 by holding a handle 15 so as to position a drill 6 on the circumference set in advance. And the first hole is bored keeping the position of the drill 6 in the transverse direction as it is. Subsequently, the substance 7 to be bored is rotated 90 deg. along with the claw body 11 so as to bore the second hole and thereafter four holes can be formed on the specified circumference with equal intervals by repeating the same operation. In this method, the possibility of error occurrence is only one time when the drill 6 is shifted, from the original position to the circumference, therefore the holes can be formed in high accuracy with simple operation.
